PAPER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 449,525, dated March81, 1891.

Application filed October 23, 1890. Serial No. 369,113. (No model.)

To all whom it may concern:

Be it known that I, CHARLES R. ELY, a citizen of the United States,residing at Champlain, in the county of Clinton and State of 5 New York,have invented new and useful Improvements in Paper-Cutting Machines, ofwhich the following is a specification.

This invention relates to improvements in paper-cutting machines; and itconsists in cer- Io tain devices and combinations set forth in thefollowing specification and claims, reference being had to theaccompanying drawings, in which Figure l is a front elevation of amachine containing my invention, the knife being shown in its raisedposition. Fig. 2 is a side elevation of a sect-ion taken 011 the lineococof Fig. 1, looking in the direction of the arrow 1. Fig. 3 is asection taken on the line y y of Fig. 5, looking in the direction ofarrow 2. Fig. at is a rear elevation of the machine. Fig. 5 is a sectiontaken on the line .2 2 of Figs. 3 and 4, looking downward. Fig. 6 is ahorizontal section in the plane 0c 93.

The machine represented is of the class in which the resistance offeredto the knife by the paper reacts upon the clamp which holds the paper onthe table.

The letter A designates the frame of the machin e, which supports atable B,upon which the paper to be cut is placed;

O is the clamp, and D the knife, both arranged above the table B. Theclamp is connected to a clamp-slide O',which is arranged under thetable, the rods Z2 b, which connect the clamp to the clamp-slide,passing through the table. The knife projects downward from theknife-stock D, which is provided with lugs (Z (Z, that extend intooblique slots at a, formed on the upper part of the frame, thearrangement being such that the knife-stock and knife when the machineis operated are moved up and down obliquely toward and away from thetable. The knife-stock D is connected to a slide E by means of the leverH, which is pivoted to the frame at e, the upper end of said lever ll.being connected to the knife-stock by a link f, while its lower end isconnected by a link h to slide E.

The

' slides O and E are uided in their motions o in vertical ways formed onthe lower part of the frame. The clamp and the knife are both operatedby means of a shaft F, which is situated between the slides and whichcarries pinions K L, that mesh with racks I J, placed on the slides Oand E, respectively. The shaft F is fitted in vertical slots g, formedin the frame of the machine, and is capable of a compound revolvingup-and-down motion. hen the clamp O and knife D are in anupperposition,the shaft F rests in the lower ends of the slots g, asshown in Figs. 2 and 3. hen a revolving motion is impart-ed to the shaftF in the direction of the arrow marked" near it in Fig. 3, the pinions KL act upon the racks I J and the clamp-slide O receives a downwardmotion, while the knifeslide E is moved upward, causing the descent ofthe knife. The shaft F remains at the lower ends of the slots g untilthe clamp O is 7c brought to bear on the paper to be cut and theclamp-slide O ceases its motion,when the pinions L, meshing with theracks J of the clamp-slide, climb upon the said racks J and cause theshaft F to travel upward in the slots 7 5 g with a revolving motion, theknife-slide E meanwhile being forced farther upward by the action of thepinions K on its racks I, so

as to cause the knife to descend still farther and complete its outthrough the paper. As the pinions L climb the racks J of the clampslide,they act upon the clamp-slide with a tendency to draw the same with theclamp downward,and since the resistance of the knife-slide E to theaction of the shaft F or its pinions K increases as the knife meets withthe resistance of the paper this increasing resistance is added to thetractive act-ion of the shaft on the clamp-slide, so that the resistanceoffered to the knife reacts upon the clamp, and the pressure of theclamp is proportionate to such resistance. The lever 11 by which theknife is connected to its slide E has its fulcrum on a pivot e, which isso ar ranged that it allows the clamp to descend 5 with greater speedthan the knife, so that the clamp is brought to bear upon the paperbefore the knife begins to cut and the correct operation of the machineis insured. Theacceleratcd movement of the clamp is increased byarranging the clamp in advance of the knife. When the clamp ceases tomove downward and the pinions L climb the racks J of the clamp-slide andcause the shaft F to rise, as before stated, the upward motion of theshaft is added to the revolving motion thereof in its action on theknife-slide with the result to increase the speed of the descent of theknife, and since this occurs just before the knife begins to cut theknife forces its way through the paper with an accelerated movement. Theadvantage thus gained is a saving of time.

A revolving motion is imparted to the traveling shaft F from adriving-shaft G, which has its hearings in journal-boxes secured to theframe A. On this shaft are loosely mounted two pinions m m, which can bethrown in gear with said shaft by a clutch mechanism M, one end of whichis provided with a friction-cap m to engage the conical hub of thepinion on, while its opposite end 2 5 is provided with a spur-disk on toengage a corresponding disk formed on the hub of the pinion m, Figs. 4and 5.

N is an intermediate shaft, which is mounted in brackets 77. a, Figs. tand 6. These 0 brackets swing loosely upon the driving-shaft G, and inthe bracket n is secured a stud n on which is mounted a pinion of, Figs.2 and 4, which gears into a pinion n firmly mounted on the intermediateshaft N. This pinion engages a cog-wheel f, firmly mounted upon 4 thetraveling shaft F, and on this shaft are loosely mounted two straps f f,which embrace the intermediate shaft N and serve to keep these twoshafts at a uniform distance apart. On the intermediate shaft N is alsomounted a cog-wheel of, which engages the pinion m on the driving-shaftG, and if this pinion m is thrown in gear with the drivingshaft G andthis shaft is turned in the direc- 5 tion of arrow 1, Fig. 2, theintermediate shaft N receives motion by the action of the pinion m uponthe cog-wheel at, and this motion is transmitted through the pinion nand cogwheel f to the traveling shaft F, causing the same to revolve inthe direction of arrow 1, (marked near the cog-wheelf in Fig. 2,) sothat the clamp O and the knife D are caused to descend, as alreadyexplained. After the knife has completed its downward stroke the clutchmechanism is reversed, so as to throw the pinion min gear with thedriving-shaft and to transmit motion to the traveling shaft F by meansof the pinions a at and cog-wheel f, Fig. 2, causing this cog-wheel, andconseoo quently the shaft F, to revolve in the direction of arrow 2,Fig. 2, whereby the clamp and the knife are both moved up and returnedto the position shown in the drawings. During the up-and-down movementsof the traveling shaft F the brackets an swing upon the driving-shaftG,but the pinions m n n and cogwheel f remain in gear witheach other,while pinion m remains in gear with cog-wheel a", so that whether thepinion m or m be clutched to the driving-shaft G, the rotary motion ofthe latter is positively transmitted by gearing to the traveling shaftF.

I am aware of the machine described 1n Patent No. 223,7 l4, granted toEdwin R. and Theodore V. Sheridan, assignees of A. Malm, January 20,1880, in which latter machine the revolving motion is transmitted fromthe drivin g-shaft to the traveling shaft through a universal joint, andthe intermediate shaft simply serves to reverse the motion of thetraveling shaft. I11 my machine the universaljoint connection isdispensed with and the intermediate shaft N serves the double purpose oftransmitting a rotary motion from the driving-shaft to the travelingshaft and also of reversing this rotary motion.

On the hub of the pinion m is placed a strap 0, which acts as a brake,whereby this pinion is prevented from turning by frictional contact,while the driving-shaft continues to rotate and the operating parts ofthe cutting-v machine are stationary. This strap is elastic and iscompressed upon the hub of the pinion m by a dog 0, which swings on astud 0', Figs. 3 and 5; and the tail end of which carries a set-screw 0which bears I upon a wedge 0 attached to the lever P, which serves toshift the clutch mechanism. When this lever is moved so as to throw theclutch-sleeve out of gear with both the pinions m and m the dog 0 ismoved so as to compress the strap 0 on the hub of the pinion m, and theaction of said strap upon the hub can be regulated by the set-screw 0hat I claim as new, and desire to secure by Letters Patent, is

1. In a paper-cutter, the combination,with a knife-stock D, a clamp O, adriving-shaft G, a traveling shaft F, and devices actuated by thedriving-shaft to operate the knifestock and clamp, of an intermediateshaft N, swinging brackets 71, a, hung on the drivingshaft andsupporting the intermediate shaft, swinging straps f f hung on thetraveling shaft and connected with the intermediate shaft, and gearingbetween the traveling, intermediate, and driving shafts, substantiallyas and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

CHARLES R. ELY.
